The dust suction pipe includes a main body and a tapered pipe located above the main body, and the diameter of the tapered pipe gradually increases from bottom to top; the pipe cover includes a cover top plate connected to the top of the dust suction pipe, a tapered surface connected below the cover top plate, and a variable diameter curved surface connected below the tapered surface; the diameter of the variable diameter curved surface gradually decreases from top to bottom, and its lower part has a section of inner wall surface relatively parallel to the outer wall surface of the tapered pipe, and a restricted flow channel for smooth air flow is formed between the variable diameter curved surface and the tapered pipe; the fan is located at the bottom of the main body to draw air into the dust suction pipe; the dust monitoring component is used to monitor the concentration of dust particles sucked into the dust suction pipe. The utility model can eliminate the interference of chaotic airflow for a large amount of dust and effectively monitor the concentration of dust particles.

[0003] However, the device has the following defects when used: although the device can eliminate the interference of chaotic airflow, when the device is used in areas with more dust (such as material factories), due to the large amount of dust and dust, a large amount of dust will be attached to the dust detection sensor when monitoring the air quality, affecting the accuracy of the dust detection sensor. To this end, we propose a dust monitoring device for material yards. Utility Model Content

[0025] Reference Figure 1-4 A dust monitoring device for a material field comprises: a dust monitoring structure, a dust removal structure and a power structure.

[0026] The dust monitoring structure is composed of a sampling head 1, a sampling tube 2, a dust detection sensor 3 and an air suction component. The sampling head 1 is fixedly installed on the upper end of the sampling tube 2. An air inlet is provided on the surface of the sampling head 1. A filter screen 19 is provided on the inner wall of the air inlet. The air suction component includes an air pump 4 and an air collecting hood 5 respectively fixedly installed on the inner wall of the sampling tube 2. The air inlet end and the air outlet end of the air pump 4 are respectively fixedly installed with a first air inlet pipe 6 and a first air outlet pipe 7. The other end of the first air inlet pipe 6 is interconnected with the air outlet end of the air collecting hood 5. The air collecting hood 5 divides the sampling tube 2 into two cavities. The driving air pump 4 can use the first air inlet pipe 6 to suck the outside air into the sampling tube 2 along the air inlet. The filter screen 19 can prevent large paper scraps and leaves in the air from entering the sampling tube 2.

[0027] The dust removal structure includes a mounting tube 8 fixedly mounted on the inner wall of the sampling tube 2, the mounting tube 8 is arranged above the air collecting hood 5, an annular brush 9 is fixedly mounted on the inner wall of the mounting tube 8, a pushing column 10 is slidably mounted on the inner wall of the mounting tube 8, a roller 11 is arranged at one end of the pushing column 10, and a dust detection sensor 3 is fixedly mounted on the other end of the pushing column 10. A base is arranged at the lower end of the sampling tube 2, and a signal wireless transmission system is arranged inside the base. The signal wireless transmission system is a prior art and is not described in detail. The dust detection sensor 3 is electrically connected to the signal wireless transmission system. When outside air enters the sampling tube 2, the dust detection sensor 3 can detect and analyze the air in the sampling tube 2, and use the signal wireless transmission system to transmit the detected information to the external cloud.

[0028] A pushing cylinder 12 is slidably installed on the surface of the sampling tube 2, and a conical groove 13 is opened on the inner wall of the pushing cylinder 12. The surface of the pushing column 10 is sleeved with a compression spring 18 that can drive the roller 11 to contact the inner wall of the conical groove 13. When the pushing cylinder 12 slides downward, the roller 11 will contact the upper end of the conical groove 13, and the dust detection sensor 3 will extend out of the mounting tube 8. Conversely, when the pushing cylinder 12 slides upward, the roller 11 will contact the lower end of the conical groove 13, and the dust detection sensor 3 will retract into the mounting tube 8. When the dust detection sensor 3 retracts or extends out of the mounting tube 8, the annular brush 9 can brush off the dust on the surface of the dust detection sensor 3.

[0029] The power structure includes a piston cylinder 14 fixedly mounted on the surface of the sampling tube 2, the inner wall of the piston cylinder 14 is slidably connected with a piston rod 15, the upper end of the piston rod 15 is fixedly connected to the lower end of the push cylinder 12, and the surface of the first air inlet pipe 6 is connected to the second air inlet pipe 16, and the surface of the first air outlet pipe 7 is connected to the second air outlet pipe 17, the other ends of the second air inlet pipe 16 and the second air outlet pipe 17 both extend to the interior of the piston cylinder 14, and valves are provided on the surfaces of the second air inlet pipe 16 and the second air outlet pipe 17.

[0030] When the air pump 4 is in the suction state, the second air inlet pipe 16 can suck out the gas in the piston cylinder 14, forcing the piston rod 15 to pull the push cylinder 12 down, so that the roller 11 can contact the conical groove 13 to drive the dust detection sensor 3 to extend out of the mounting tube 8. When the dust detection sensor 3 extends out of the mounting tube 8, the annular brush 9 can brush off the dust on the surface of the dust detection sensor 3. When the air detection is completed, the valve on the surface of the second air outlet pipe 17 is opened, and the air pump 4 can be used to inject gas into the piston cylinder 14, forcing the piston rod 15 to rise and drive the push cylinder 12 to reset, thereby driving the dust detection sensor 3 to retract into the mounting tube 8. On the one hand, it can prepare for the next extension of the mounting tube 8, and on the other hand, the annular brush 9 can be used again to clean the dust detection sensor 3.

[0031] Compared with the existing technology, the device uses an air pump 4 to suck external air into the sampling tube 2 for analysis and monitoring. At the same time, the air pump 4 can drive the dust removal structure to clean the dust detection sensor 3 each time it inhales air, thereby avoiding the problem of a large amount of dust adhering to the surface of the dust detection sensor 3 affecting its accuracy.

[0032] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
